sa e Winge-'r STOVE.

Applicatonnled March 31. .1921. Serial No. 45T/,4545.

To all whom t may concern;

it known that l, LEON NANQUETTE, a citizen oit the Republic yof France, and resident ol Paris, France, post-office address 19 Menue de Villiers, have invented anew and useful fitcve which apparatus is fully set :forth in the following specilication.

4This invention relates to a continuously burning stove, more particularly intended for burning wood, butin which coke or anthracite coal can also be burned. t is characterized by the combustion beingv limited to the lower portion of the stove, and by the combustion gases on escaping from the aforesaid lower portion passing into an annular chamber or drum arranged in the upper 'portion oi' thestove so as to enable the maximum of the calorilic power ot the fuel to be utilized.

A construction according to `the invention is illustrated by way o' example in vthe accompanying drawing in which Figure 1 is a vertical section of the stove;

Figure 2 is a view partly in elevation and partly in section;

Figure 3 is a horizontal cross-section onl line 3 3 of Figure l;

Fie-ure i is a horizontal cross-section on line cl-e of Figure 1.

l is the casing, preferably of sheet metal, supported by the base 2 resting :on the ,aground by ineans of feet 3. The casing l is lined inside with a refractory earth acket il, both the jacket and the casing terminating at about the center of the stove. The lining is removed, however`r at the point where the hereina'iter-described door and smoke conduit or iue are located. ln the base is arranged an ash pit 5, the front part of which has openings 6 tor the passage ofthe air required for the combustion7 said openings beingcontrolled by ineens of a sliding damper. The casing is provided with a door T which can be solid or have windows of mica or other similar transparent 1naterial. @pposite the door are arranged two vertical deliectors 8 intended to prevent the lighted wood 'from coming into contact with the door. At the lower end oit the casing arranged a horizontalplate 9 provided with holes and resting on a grate 10. At the front portion ot the plate 9 is provided an opening 11 for the passage of the air. At the rear portion ot the casing7 about the middle of its height, is arranged a cast iron flue 12 forming a smoke conduitaffording passage to the gases going to the heating drinn, which latter is indicated generally at 13. f

The `heating;l drinn is arranged immediately vabove the casing l, and is constituted by two concentric cylinders: an inner cylnider 14C, preferably of cast iron, tori/nine` an eX; sion oi. the `retractory lining7 and outer cylinder 3.6 which can be oit sheet nietal or cast iron and which is connected bv means ot a shoulder to said casing.` f u LMidway between the top and bottom ot the drumisarranged a horizontal partition 1"? provided with openings 18, 18 (Figure 3) so arrangrged that the gases entering` through the/conduit 12, Vpass into the lower annular spaceY then upwardly through the ogiiening 1S into the upper annular space, and escape through the opening` 18into the smoke outlet 1i) which is separated by 'a diaphragm 26 troni the bottom part ot the drum. in the inner cylinder la are provided openings 2O :to the escape ot the gases and vapours ot distillation, and an opening 21 closed by a dan'iper 22, the opening of which gives a. direct draft in the smoke outlet.

The drum is surmounted by a top 24 with a sand packing joint 25 carrying the cover 23 which closes the charging openinO'.

The working ot the apparatus is as :tollows: 'the sticks of wood are introduced ver tically into the stove through the upper opening` after removal of the cover 23, and they rest on the plate 9. Air enters through the orifices 6 el' the ash pit door and passes through the openingl 11; the combustion gases escape through the conduit 12. These gases rise, pass into the bottom chamber or compartment oi the drum 13 and then through the opening; 18 into the upper chain.-

ber or Vcornpart-ment thereof, in order to escape from it through the opening 18 and the conduit 19. The ydistillation gases and steam escape through the holes 20. Y

The drattis regulated by means orp the sliding damper oit the ash pit door which closes to a greater or less extent the open ings G and7 it necessary, by means et the damper 22 uncovering the opening 21 which accelerates the combustion. rlhe removal ot ashes is eilected by operating' the grate in some suitable manner.

lt will be clear from the preceding that the air passes horizontally through the mass of tuch and that the combustion is limited to the bottoni part of the stove, which avoids any escape of smoke or fumes. Owing-to the provision, of the drum, the combustion gases give olil the greatest portion of their heat, which results in a considerable economy of fuel. By removing the plate 97 the stove could also be used for burning coke or anthracite coal.

a What l claim is:

l. In a stove, the combination of a casing,

havinoa orate in the lower ortion thereof' .y .c e. 7 a lining or refractory material within the casing, said lining having a portion thereofl vend into the bottom of the drum, so as to draw the products of' combustion from the fuel on thel grate directly into the flue and to discharge them into the drum; means in said drum for causing the products of combustion to `travel therethrough in an upwardly-directed spiral path; and an outlet flue communicating with the drum.

2, In a stove, the combination of a cas-v ing having a grate in the lower portion thereof;` an' annular drum mounted on top or the casing and provided with a cover for closing` its open central space; a conduit opening at its lower end into the casing at a point close the grate, and at its upper end into the bottom of the drum, so as to draw the products of combustion from the fuel onthe grate directly into the conduit and to discharge them 'into the drum; a partition disposed horizontally within the drum midwayv between its top and bottom and provided with an opening which is located at the opposite side of the drum from the point which said conduit opens thereinto, whereby the products or' combustion will becaused to travel through and around the lower part of the drum before reaching said opening and entering the upper part of the drum; andan outlet `flue communicating with the drum and disposed on the same side thereof as'the' conduit. a i n In testimony whereofl I have signed this specificationin the presence or" two subscribing witnesses.
